Hi Angus,

Thank you for your explaining.
This server access from customers.
My company account access from smartphone, pc, vdi with different node.
I was just my imagined 256 is ok.
You are right.

Nori

Hi

I do not remember this.
But few people use same account in my case. 
From smartphone, pc , vdi.
So, 50 is ok.
You can also change dovecot.conf.
If it is better, you can use.

Regards,
Nori

Re: [qmailtoaster] Simultaneous pop3 connections from two devices

[Angus McIntyre]

I doubt a single user would ever need 256 simultaneous connections, but 
-- judging by the name -- the setting might specify the number of 
connections allowed from a single IP, which would be different.


If you had a large number of users on a NAT'ted network, so that they 
looked to the server as if they were coming in from a single IP, maybe 
bumping the allowed connections up to 256 would make sense?

Hi Eric:

We just installed another CDB version of the QMT. It's working
great - thanks. I have a question.

We have a situation where a user wants to have multiple devices
concurrently connecting via pop3 to his email account so that each
device is downloading messages. He is finding that the second
device is getting a message that only one user can connect to his
pop3 account at a time. Seems to me this used to work on the older
QMT's. Is this behavior normal?

Thanks, but why would any user need 256 simultaneous pop3 connections?

We use Dovecot now as opposed to Courier IMAP, I'm not sure about that 
question.
